@Zale101

Answer 5

the first term of the trinomial, namely 81x^2, i the first product of the first terms of the factors namely 9x and 9x.
9x X 9x=81x^2.

Answer 6

the middle term of the trinomial, namely 36(or 36x), is the subtract of the product of the inner terms, namely 2 and 9x, and the product of the outer terms, namely 9x and 2.

Answer 7

the last term of the trinomial, namely 4, is the product of the last terms of the factors, 2 and 2.

Answer 8

2 X 2=4. You simply find the factors of the first term(81x) and last term(4) and they will give you the middle term which is 36.
